摘要：

We study gravity in 2 + 1 dimensions on the manifold M = D2 × R. A specific choice of boundary conditions leads to an equivalence of the system with a chiral Wess-Zumino-Novikov-Witten model associated with the group ISO(2,1). The model is written on the boundary S1 × R of M. We find induced representations of the corresponding Kac-Moody and Virasoro algebras with zero Virasoro anomaly. © 1990.
